PATENT IMPROVEMENT IN BED-BOTTOMS.

Specification forming part of Letters Patent No. 119,862, dated October 10,-1871.

To all whom it may concern.-

Beit known that I, GEORGE D. LEONARD, of Chicago, in the county oi' Cook and State of Illinois, have invented certain new and useful Improvements in Spring-Bottom Bedsteads,. of which the following is a specification, reference being had to the accompanying drawing, which forms a part hereof.

My invention is intended to be applicable to any bedstead. I am aware that bed-bottoms have heretofore vbeen used in which a similar arrangement of slats and blocks has been used, and that the slats and blocks have been arranged in pairs, and so as to bear upon levers which occupy a position similar to that occupied by my springs. Such an arrangement is shown and described in Letters Patent No. 92,740, issued to George W. Morrill, July 20, 1869, for improved spring' bed-bottom. Morrill and others have depended for elasticity upon rubber rings or loops, while I depend for that purpose upon Wooden springs, and I use springs especially constructed for iiexibility. Rubber loops or rings are liable to break and soon wear out or lose their elasticity by constant use, and my improvement enables me to dispense with their use; and it consists in the combination and arrangement of slats, blocks, and wooden springs, hereafter fully described, the object of my invention being to make a cheap and durable spring-bottom for bedsteads.

Figure lis a top or plan view of a bedstead provided with my improved spring-bottom. Fig. 2 is a longitudinal transverse sectional view of the same through the line .r x.

A is a bedstead-frame. B are the slats which support the bed. C are end blocks, and C is the central block, to which the slats B are attached. D are Wooden springs, and E are the rails of the bedstead. The slats B may be at tached to the blocks C and C in pairs, as shown, and these slats or pairs of slats may be attached to each other by weaving strips of leather or other suitable material about them. The springs D are chamfered off or made gradually thin from one end to the other, and one end has a bearing upon the central block C', while the other end has a bearing upon one of the rails E, as shown.

By this construction and arrangement I produce a spring-bottom having an elasticity corresponding to the inclination, length, thickness, and nature of the wood of the springs D. The springs D may be readily removed, and if they should become bent by use or otherwise, so as not to operate properly, their concave side may be turned downward, when they will again properly operate. The bearings may be packed or lined with any suitable material to prevent squeakin g. The end blocks C are so cut and fitted to the springs D as to rest firmly and securely thereon and prevent the slats B from rocking too much, and the springs D are nicely fitted into their bearings on the rails E for the same purpose, as shown.

F are leather strips or strips of any suitable material, one end of which is attached to one of the rails E and the other to one of the end blocks C, as shown. These bands are sufficiently tight to keep the slats B from sliding on the springs D either toward the foot or head of the bed, so as not to scratch and injure the latter.

I do not claim arranging the slats in pairs, nor weaving about them in the manner described. Neither do I claim, broadly, the wooden springs D, nor supporting the slats upon them; but

What I claim, and desire to secure by Letters Patent, is-

The combination and arrangement of the slats B, blocks C and C', and the springs D when the springs D have bearings and operate substantially as shown and described.
